Title (EN) METHOD FOR PREPARING L-METHIONINE CRYSTALS USING CRYSTALLIZATION TECHNIQUE
(FR) PROCÉDÉ DE PRÉPARATION DE CRISTAUX DE L-MÉTHIONINE À L'AIDE D'UNE TECHNIQUE DE CRISTALLISATION
(KO) 결정화 기술을 이용한 L-메티오닌 결정의 제조방법
Abstract:
(EN) The present application relates to a method for preparing L-methionine crystals with improved bulk density. As the L-methionine crystals prepared according to the method for preparing L-methionine crystals of the present application may have a bulk density of up to 800 g/L, the L-methionine crystals are expected to reduce storage and transport costs of L-methionine powder and improve working environments due to improved fluidity of the powder.
(FR) La présente invention concerne un procédé de préparation de cristaux de L-méthionine ayant une densité apparente améliorée. Les cristaux de L-méthionine préparés selon le procédé de préparation de la présente invention peuvent avoir une densité apparente allant jusqu'à 800 g/L, ce qui leur permet de réduire les coûts de stockage et de transport de la poudre de L-méthionine et d'améliorer les environnements de travail en raison de la fluidité développée de la poudre.
(KO) 본 출원은 겉보기 밀도가 개선된 L-메티오닌 결정의 제조방법에 관한 것이다. 본 출원의 L-메티오닌 결정의 제조방법에 따라 제조된 L-메티오닌 결정은 겉보기 밀도가 최대 800g/L까지 가능한 것으로 L-메티오닌 분말의 저장 및 수송비용의 절감 및 분말의 유동 특성 향상에 의한 조업환경의 개선까지 기대할 수 있다.
